| 122 | * @brief |
| 123 | * Queues the current buffer, gets back a another buffer for encoding with corrent |
| 124 | * picture type |
| 125 | * |
| 126 | * @par Description: |
| 127 | * This function performs 3 distinct but related functions. |
| 128 | * 1) Maintains an input queue [Note the the term queue donot imply a |
| 129 | * first-in first-out logic here] that queues input and dequeues them so |
| 130 | * that input frames can be encoded at any predetermined encoding order |
| 131 | * 2) Uses RC library to decide which frame must be encoded in current pass |
| 132 | * and which picture type it must be encoded to. |
| 133 | * 3) Uses RC library to decide the QP at which current frame has to be |
| 134 | * encoded |
| 135 | * 4) Determines if the current picture must be encoded or not based on |
| 136 | * PRE-ENC skip |
| 137 | * |
| 138 | * Input queue is used for storing input buffers till they are used for |
| 139 | * encoding. This queue is maintained at ps_codec->as_inp_list. Whenever a |
| 140 | * valid input comes, it is added to the end of queue. This same input is |
| 141 | * added to RC queue using the identifier as ps_codec->i4_pic_cnt. Hence any |
| 142 | * pic from RC can be located in the input queue easily. |
| 143 | * |
| 144 | * The dequeue operation does not start till we have ps_codec->s_cfg.u4_max_num_bframes |
| 145 | * frames in the queue. THis is done in order to ensure that once output starts |
| 146 | * we will have a constant stream of output with no gaps. |
| 147 | * |
| 148 | * THe output frame order is governed by RC library. When ever we dequeue a |
| 149 | * buffer from RC library, it ensures that we will get them in encoding order |
| 150 | * With the output of RC library, we can use the picture id to dequeue the |
| 151 | * corresponding buffer from input queue and encode it. |
| 152 | * |
| 153 | * Condition at the end of stream. |
| 154 | * ------------------------------- |
| 155 | * At the last valid buffer from the app, we will get ps_ive_ip->u4_is_last |
| 156 | * to be set. This will the given to lib when appropriate input buffer is |
| 157 | * given to encoding. |
| 158 | * |
| 159 | * Since we have to output is not in sync with input, we will have frames to |
| 160 | * encode even after we recive the last vaild input buffer. Hence we have to |
| 161 | * make sure that we donot queue any new buffers once we get the flag [It may |
| 162 | * mess up GOP ?]. This is acheived by setting ps_codec->i4_last_inp_buff_received |
| 163 | * to act as a permenent marker for last frame recived [This may not be needed, |
| 164 | * because in our current app, all buffers after the last are marked as last. |
| 165 | * But can we rely on that?] . Hence after this flgag is set no new buffers are |
| 166 | * queued. |
| 167 | * |
| 168 | * @param[in] ps_codec |
| 169 | * Pointer to codec descriptor |
| 170 | * |
| 171 | * @param[in] ps_ive_ip |
| 172 | * Current input buffer to the encoder |
| 173 | * |
| 174 | * @param[out] ps_inp |
| 175 | * Buffer to be encoded in the current pass |
| 176 | * |
| 177 | * @returns |
| 178 | * Flag indicating if we have a pre-enc skip or not |
| 179 | * |
| 180 | * @remarks |
| 181 | * TODO (bpic) |
| 182 | * The check for null ans is last is redudent. |
| 183 | * Need to see if we can remove it |

| 365 | * |
| 366 | * In encoding streams with B frames it may happen that we have a B frame |
| 367 | * at the end without a P/I frame after it. Hence when we are dequeing from |
| 368 | * the RC, it will return the P frame [next in display order but before in |
| 369 | * encoding order] first. Since the dequeue happens for an invalid frame we |
| 370 | * will get a frame with null buff and set u4_is_last. Hence lib with return |
| 371 | * last frame flag at this point and will stop encoding. |
| 372 | * |
| 373 | * Since for the last B frame, we does not have the forward ref frame |
| 374 | * it makes sense to force it into P. |
| 375 | * |
| 376 | * To solve this, in case the current frame is P and if the last frame flag |
| 377 | * is set, we need to see if there is and pending B frames. If there are any, |
| 378 | * we should just encode that picture as the current P frame and set |
| 379 | * that B frame as the last frame. Hence the encoder will terminate naturally |
| 380 | * once that B-frame is encoded after all the in between frames. |
| 381 | * |
| 382 | * Since we cannot touch RC stack directly, the option of actually swapping |
| 383 | * frames in RC is ruled out. We have to modify the as_inp_list to simulate |
| 384 | * such a behavior by RC. We can do that by |
| 385 | * 1) Search through as_inp_list to locate the largest u4_timestamp_low less |
| 386 | * than current u4_timestamp_low. This will give us the last B frame before |
| 387 | * the current P frame. Note that this will handle pre encode skip too since |
| 388 | * queue happens after pre enc skip. |
| 389 | * 2) Swap the position in as_inp_list. Hence now the last B frame is |
| 390 | * encoded as P frame. And the new last B frame will have u4_is_last |
| 391 | * set so that encoder will end naturally once we reached that B frame |
| 392 | * or any subsequent frame. Also the current GOP will have 1 less B frame |
| 393 | * Since we are swapping, the poc will also be in-order. |
| 394 | * 3) In case we have an IPP stream, the result of our search will be an |
| 395 | * I/P frame which is already encoded. Thus swap and encode will result |
| 396 | * in encoding of duplicate frames. Hence to avoid this we will only |
| 397 | * have this work around in case of u4_num_bframes > 0. |
| 398 | * |
| 399 | * In case we have forced an I/IDR frame In between this P frame and |
| 400 | * the last B frame -> This cannot happen as the current P frame is |
| 401 | * supposed to have u4_is_last set. Thus forcing an I/ IDR after this |
| 402 | * is illogical. |
| 403 | * |
| 404 | * In cae if we have forced an I such that the frame just before last frame |
| 405 | * in is I/P -> This case will never arise. Since we have a closed GOP now, |
| 406 | * once we force an I, the gop gets reset, hence there will be a B between |
| 407 | * I/P and I/P. |
